Euphorbia colliculina is one of several medusa head Euphorbias.
The plants occur only the Oudtshoorn district. There are however similar looking plants from other areas that may need further study. The red glands in the flower structure, as mentioned in the original description, present somewhat of a mystery as these are seldom observed in the plants from around Oudtshoorn.
Locally the plants are referred to as "Vingerpol".
Some larger related plants are found between Oudtshoorn and George.
Propagation is from seed.
